=head1 NAME

ExtUtils::MM::Utils - ExtUtils::MM methods without dependency on ExtUtils::MakeMaker

=head1 SYNOPSIS

    require ExtUtils::MM::Utils;
    MM->maybe_command($file);

=head1 DESCRIPTION

This is a collection of L<ExtUtils::MM> subroutines that are used by many
other modules but that do not need full-featured L<ExtUtils::MakeMaker>. The
issue with L<ExtUtils::MakeMaker> is it pulls in Perl header files and that is
an overkill for small subroutines.

An example is the L<IPC::Cmd> that caused installing GCC just because of
three-line I<maybe_command()> from L<ExtUtils::MM_Unix>.

The intentions is to use L<ExtUtils::MM::Utils> instead of
L<ExtUtils::MakeMaker> for these trivial methods. You can still call them via
L<MM> class name.

=head1 METHODS

These methods are copied from L<ExtUtils::MM_Unix>. Other operating systems
are not supported yet. The reason is this
